摘　　要：对近零能耗社区负荷进行预测,构建含多元储能的近零能耗社区供能系统。针对该系统提出一种双层迭代协同优化方法,对系统配置及运行进行优化。利用该系统为不同公共建筑占比的近零能耗社区供能,实现社区供能的热电调蓄。从能源效益、经济效益、环境效益方面对系统进行综合评价。结果显示:与分供系统相比,新型系统在给公共建筑占比为30%的近零能耗社区供能时,一次能源节约率和年值节约率最高可达51.1%和18.8%,公共建筑占比为50%的供能系统综合评价值最高,为0.357 3。The near-zero energy community load is predicted and the near-zero energy community energy supply system with multiple energy storage is constructed.For this system,a two-level iterative collaborative optimization method is proposed to optimize the system configuration and operation.The system is used to supply energy to near-zero energy communities with different public building percentages,and to realize thermoelectric storage for community energy supply.The system is comprehensively evaluated in terms of energy efficiency,economic efficiency,and environmental efficiency.The results show that the primary energy saving rate and annual value saving rate of the new system can reach up to 51.1% and 18.8%,when supplying energy to near-zero energy communities with 30% of public buildings compared with the sub-supply system.The supply system with 50% of public buildings achieves the highest comprehensive evaluation value of 0.357 3.
